It is either carcinogens or viruses (I think the first) I hope this helps!

</span>The milkweed is the primary producer in the
ecosystem. It manufactures food from the abiotic factors in the soil such as
nitrates and water and those in the atmosphere such as carbon-dioxide and
sunlight. The milk weed is then fed on by the caterpillar and a primary
consumer. The caterpillar is then fed on the mocking bird (secondary consumer)
<span>b)
</span>Increased human population growth and their activities
have resulted in the emission of carbon dioxide and other greenhouse gases in
the atmosphere. This has increased the global temperature. This increase of
global temperature increase ocean temperatures causing coral bleaching.
Another example is depletion of water sources
by human activities hence causing drought. Drought reduces the amount of
vegetation growth due to scarcity of water in the soil (due to lowering of the
water table) for plant growth.
Ecology is the science that studies the interaction between living beings and the environment in which they live.
<h3>How can I help with conservation?</h3>
- Buy recycled paper avoiding the death of more trees
- Have a recycling bin for paper, plastic, metal and glass, to reduce the environmental damage in waste and for the waste to be reused
- Recycle toner and ink cartridges from empty printers, to avoid polluting rivers and streams.
- If possible buy remanufactured cartridges, avoiding environmental impact
- Recycle old newspapers, avoiding the death of more trees.
<h3>What is the evidence for evolution?</h3>
- Anatomy. Species may share similar physical features because those features were present in a common ancestor (homologous structures).
- Molecular biology. DNA and genetic code reflect the common ancestry of life
With this information, we can conclude that Ecology is concerned with the living beings on the planet and their relationships with each other and with the environment.
